TYPEWRITING-MACI-IINE.

Specification of Letters Patent.

Patented Oct. 11, 19.21.

Application filed December 28v 1917. Serial No. 209,247.

in which the web which is longitudinally folded is fed around the revoluble platen of a typewriting machine, with carbon sheets placed between the plies of the web, these carbon sheets being shiftable backwardly to cooperate with fresh portions of the web from time to time as required, and the platen being displaceable to permit the webs to be straightened out sufliciently to allow for this backward shifting of the carbons.

One feature of the present invention relates to a provision whereby carbons may be carried between the plies of a web whose folds are all along one side, one fold within another instead of being upon alternate sides, as in said Wernery and'Smith patent. In order to accomplish this, I provide for holding the carbon sheets a set of arms or blades which are all attached to a support on one side of the carbon carrier and all projecting toward the opposite side of the latter from said support, so as to enable the carbons to enter between all the plies in the web.

In order to overcome the difficulty presented by seeking to mount so many blades at one side of the machine, I employ, in connection with the usual number of mounts or steps, a larger number of blades, placing two or more blades upon each of said mounts or steps. Moreover, I provide for each mount or step two bearings or securing means, one for each blade, so that one of the blades may be omitted from one or more of the steps or mounts if the bladesare not all needed for the particular work in hand. It will be understood that this forms a very compact arrangement, which is a desideratum because it reduces the extent of unused 'mounts for said blades.

carbon at the heads of the sheets; the extent of such unused portion depending upon the dlstance to which the blades are strung along the machine from front to rear. and a spreading arrangement of the blades being avolded by the expedient of doubling up, as described. Moreover, the doubling up of the blades avoids the necessity of ere tending the run or range of action of the carbon carrier which wouldbe required if the blades were placed one behind another- Provision is further made for permitting the resetting of some of the blades when required for use with fanfold webs, in said VVernery and Smith patent.

Other features and advantages will here inafter appear. I

In the accompanying drawings,

Figure 1 is a perspective view of an Underwood front-strike typewriting machine of the class set forth in said Wernery and Smith patent, showing the same adapted fora nest of folded plies of web.

Fig. 2 is a cross-sectional front elevation, showing dia raminatically the relationship of the nest of folds and the carboncarrying blades. i

Fig. 3 is a similar elevation, showing the parts rearranged for a fan-fold web;

F 4 is a perspective view of parts slightly separated to show their structure.

Fig. 5 shows diagrammatically how a carbon is folded back over one of the lefthand blades of Fig. 3.

There is led into the machine a web 10, comprising a set of folded plies 11, each folded along the middle and one fold tucked into another. The carbons 12 are interleaved between the plies 11 and carried upon the blades 13, which all extend inwardly from one side of the carbon carrier or slide 1 1, which, by means of'a handle, not shown, i

is used for drawing back all of the carbons to underlie fresh portions of the web as soon as one portion has been" typed, as in said patent. Upon one side of this carbon carrier are provided steps 15, which serve as Certain of said blades are mounted directly upon the steps by means 01 dowel pins or studs 16, which project down from the hubs of the blades into holes 17 forming sockets in the steps, each blade having a clip 18 for holding the carbon 12 thereon. The clip 18 is pivoted on a headed stud 18 forming a finger- 1ece.

Each blade 15 in the set may be surmounted by another blade 19, which may have dowels 20 topress down into other holes 21, forming sockets in said steps; said dowels 20 also passing through holes 22, that are formed in the first-mentioned blades 13 and the clips 18 whereby the clips 18 are locked in closed position. The steps are *broadened to give room for the two sets of blades 13, 19 in each case, and, if desired, the broadened steps may be formed by placing together side by side two single sets of steps 15, 15, as illustrated in Figs. 2 and 4-. The surmounting or overlying blades19 thus rest upon and are anchored to the lower blades 18, but, nevertheless, are secured to the steps 15 by means of the pins '20. The upper blades 19 are raised above the lower blades 13 bymeans of distance blocks or spacers- 19 provided on the lower sides of. the pin-carrying ends of the upper blades 19, as shown in Figs. 1, to 1, inclusive.

The free ends of the blades 13 and 19 are in substantial alinement, but the upper blades 19 are shorter than the lower blades 13 and have their pin-carrying ends displaced in-. wardly sufficiently to avoid interference with the finger-pieces 18 of the lower blades 13. r i

Thus, it will be seen that a large number of blades can be compactly fitted in a very small space with the benefit of economizing all the carbon sheets, and the. further benefit of making it unnecessary to lengthen the throw of the carbon'carrier which would be the case if all of the blades which project the same way were a: "anged one behind an;

other, as in saidpatent.

In order to increase the range of useluh ness of the machnie, I also make provision for resetting or rearranging the blades as required for fan-fold work, so-tl1e machine may accommodate either the nest of folds.v as in Figs. 1 and 2, orthe fan-fold 23, as

in Fig. 0. For thispurpose it is necessary to takeoff the upper blades 19 in each pair and turn them end over end and set them upon stepsor mounts 15", which areqnorided upon the opposite side of the carbon carriage 14;. These steps are higher than the corresponding steps 15 in the first-described set, so that the blades 19 mounted thereon will lie at substantially the same levels, respectively, as before. These additional steps are provided with holes or sockets for the blade dowels 20. The carbons 12 need to be attached in a slightly different manner to the blades 19 arranged P 1 t is s de f the machine. They t be inserted up-side down in the blades and with the sheets extending backwardly therefrom, and then the sheet 12 must be folded forwardly under the blade 19, as at Fig. 5. The blade 19 is provided with a clip 25 to hold the carbon 12, as in Patent No. 1,177,546, dated March 28, 1916.- The clip 25 is pivoted 011a pin 25 having a head to provide a finger-piece.

The innerset of'steps 15 may be made detachable 'to permit transposition thereof, as suggested in Figs. 2 and 3. For this purpose, the latternamed steps are attached to the carbon carriage 1d bymeans of screws 26, enterlng holes 27 in the carriage. When the machine operates on webs folded and then the detachable steps 15 can be readily transferred to a suitable seat on the opposite side of the carbon carriage, as indicated in Fig. 3, where they are deslgnated by the reference character 15". It willbe seenthat the seat at the left in Figs. 2 and 3 is higher than that at the right, so that the upper blades, although resting directly on the steps 15 at the left, as shownin Fig. 3, will be at thesame heights as when superintposed on the lower blades, as shown in F 1g,

2. The height of the seat at the left is greater than that at the right by the thickness ofa lower blade 13 together with its clip 18. The heightsof the supports and the thickness of the spacers 19 are such as to provide proper vertical spacing of the superimposed holders or blades 13 and 19,'

whether the upper blades 19 are supported at the right of the machine, as in Figs. 1, 2

and 1, or at the left, as in Fig, Onifdesired, the machine may be provided with the three sets of steps or mounts 15, 15 and I 15", as illustrated in Figs. 1 and In any event, the machine can be employed for work either on webs composed of nests of:

folds or on fan-folded webs, at o ation; The

' operation is the same in either case, sarethe 28, upon which they are advanced by the usualfced rolls to the printing line. I The carbon carriage l4 meanwhile is drawn along the rails 29, as the typing is being done. hen this has been. accomplished.

the platen is'separated from the feed rolls described in the r te tS=-.,e 1d th webs.

Variations may be resorted to within the webs and carbons being released, the carbon carriage and holders are moved longitudinally of the folded plies to shift the carbons back to new positions along the scope of the invention, and portions of the im )rovementsmay be used without others.
